Android calls over BT

Hi guys. I am working on a project that makes use of Android-x86 and a Mini-ITX setup with a multitouch monitor. 4 questions: can I connect to my phone via Bluetooth to make calls, how can I increase the Notifications bar (the top bar thingy), how can I move the location of the apps tray (by default on Android-x86, it slides in from the right), and is there a way to make apps run as a "screensaver"?
